Question # 40

A customer decides to use 2 large servers to load balance a mix of large and small virtual machines. Each server has 64GB of RAM and 8 quad-core CPUs.

What two issues will the customer likely discover when one of the servers fails?

Not all of the virtualmachines on the failed server will be able to restart on the remaining serverdue to lack of vCPUs.

Not all of the virtual machines on the failed server will be able to restart on the remaining serverdue to lack of memory.

Live migration will be unavailable until the second server is restored.

Not all of the virtual machines on the failed server will be able to restart on the remaining serverdue to lack of vNICs.

Not all of the virtual machines on the failed server will be able to restart on theremaining serverdue to lack of shared storage.
